diego the dualmaster

Hi, I just got done training some critical spells and astral spell. At the end diego said he'd give me a token, I got no clue what he gave me. No spells have been added, so I really don't know what the training was about when I don't have anything to use it with. I am a lvl 50 death wizard.Could someone plz tell me what this was all aboutThanks,Haley Hexcaster
